Rooftop PV business models in India and Brazil - a comparative analysis.

Household PV markets are expanding at a rapid pace in developing nations due to significant technology cost reductions achieved during the last decade as well as supporting governmental policies. However, the regulatory context of each country and the emergence of business models inside each market also play a significant role in this diffusion. This paper compares how Indian and Brazilian business models for residential PV market are being structured, either in the gridconnected or in the stand-alone PV markets. The upfront capital investment to purchase and install a PV system is still an obstacle for an average household in the two nations, and this affects business models. We compare features such as type of service, value proposition, revenue model, communication channels, costs and technologies, and discuss how the emerging business models are contributing to enhance access to electricity. Finally, we identify the main barriers for innovative models in each context, including third-party ownership, utility-owned and crowd-funding. We discuss how the current regulatory frameworks support or prevent such models to emerge in both household PV markets. [ABSTRACT FROM AUTHOR]
